Abstract (en)

[origin: EP2338645A2] A technique for providing a user with effective information in performing an operation is provided in a power tool having a speed change mechanism. A power tool has a speed change mechanism that is adapted to switch a tool bit 113 from first drive mode in which the tool bit is driven at high speed and low torque to second drive mode in which the tool bit is driven at low speed and high torque, according to load on the tool bit 113. The power tool includes detecting and indicating device 161, 163, 167 that are adapted to detect a predetermined status condition of the first drive mode and indicate switching from the first drive mode to the second drive mode before switching to the second drive mode.
